Question about Onkyo TX-DS474 Receiver
All the other speaker and line outputs work fine. I have followed the programming and troubleshooting instructions in the Instruction Manual and also did the microprocessor reset procedure from the service manual. I reseated all the pcb connectors and tested the speaker driver transistors for opens, shorts, and cracked solder. The customer said those outputs had been working and stopped. I am testing with my own speakers. Is there a history of this problem on this model? The way the unit is made, it will be a big job to get everything in a position where I can follow all the control and signal information with a scope.
1-speaker cable is not connected.
2-surround mode button is set to stereo.
3-center level is set to minimum.
4-center speaker is set to no.
